The biggest threat to central heating system performance is widely recognised as black iron oxide sludge, which accounts for more than 95 per cent of system damaging particles.
Magnetite and other particles leech into system water during everyday operation and, if left untreated, ongoing contamination will eventually lead to noisy boiler operation, radiator cold spots and ultimately the breakdown of the system.
One of the most innovative solutions that prevents these issues is magnetic filtration. Designed to remove the sludge that causes blocked pipework and damaged boilers, it was pioneered in the UK almost a decade ago.
Independent research from GASTEC into the impact of black iron oxide sludge has confirmed that the adoption of magnetic filtration technology can significantly improve central heating system performance.
The tests undertaken demonstrate that filters installed on new and existing systems is effective in the collection, removal and ongoing reduction of black iron oxide.
As a result of adopting magnetic filtration, a typical three-bedroom household can reduce its heating energy consumption by 6 per cent a year.
The research findings also demonstrate reductions in carbon emissions of up to 250 kg annually for a similar three-bedroom dwelling. This also provides installers and engineers with a strong message to take to their customers.
As the maintenance process is often carried out in front of the homeowner, they can demonstrate how important this approach is in extending the operational life of the boiler, potentially beyond the industry accepted life span of 12-15 years.
